74LVT16652ADGG End of life

3.3 V 16-bit bus transceiver/register; 3-state

The 74LVT16652A is a high-performance BiCMOS product designed for VCC operation at 3.3 V. The device can be used as two 8-bit transceivers or one 16-bit transceiver.

Complimentary output enable (OEAB and OEBA) inputs are provided to control the transceiver functions. Select control (SAB and SBA) inputs are provided to select whether real-time or stored data is transferred. A LOW input level selects real-time data, and a HIGH input level selects stored data. The circuitry used for select control eliminates the typical decoding glitch that occurs in a multiplexer during the transition between stored and real-time data.

Data on the A or B bus, or both, can be stored in the internal flip-flops by LOW-to-HIGH transitions at the appropriate clock (CPAB or CPBA) inputs regardless of the levels on the select control or output enable inputs. When SAB and SBA are in real-time transfer mode, it is possible to store data without using the internal D-type flip-flops by simultaneously enabling OEAB and OEBA. In this configuration, each output reinforces its input. Thus, when all other data sources to the two sets of bus lines are at high- impedance, each set of bus lines remains at its last level configuration.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
